Now that you posted that, it makes perfect sense. Going too fast and totally forgot about it. I think we've been in the winter formula in Michigan for a few weeks now. Thanks.

I do have a CAI and mufflers, otherwise completely stock. 33,xxx miles. I use the cheap gas. Unless you have a built motor I wouldn't suggest running higher octane.

I'm running 89octane and ride about 80% interstate at 80MPH. Getting 23.5mpg consistently with Automatic.

Higher octane is just more knock resistant. If you're not running high compression it's a waste. Fail?

Long, hot (90+) trips or a *really* heavy load. Other than that >87 is a waste.

LFX's are high compression motors (11.5:1) and they like 91 octane. They run fine on 87 but timing IS being pulled, you can watch the KR with any cheap scantool. I used to feel it most at part throttle acceleration. Makes more power with 91 than 87, no doubt.

You can't get more power from more octane. You can compress higher octane fuel more before it ignites by itself. That is all. If your engine is designed to highly compress the fuel (as in a turbo or other such high performance performance feature) then you actually NEED a higher octane rating. Octane rating is a measure of it's ability to compress before spontaneous combustion. If your engine (LFX) does not compress the fuel enough to cause spontaneous combustion, the money you spend on a higher octane rating is wasted.

A stock LFX runs fine on 87, but it pulls timing (knock reduction) to be able to do it. If you run 91 it will pull a lot less timing if any at all. Less timing = less power, more timing = more power. So yes 91 will make more power in our cars than 87 will. But not because "91 makes more power" but because 91 allows the ecm to run the timing it was designed to run. It just has the ability to instantly reduce the timing as soon as knock is detected. That way the masses can fill up with 87 and be happy.
